Thanks again for looking at these reports. I have thankfully essentially
completed my implementation of history for ngspice (an open-source
successor to SPICE 3F5 with a csh-like front end that handles parsing a bit
differently than a shell would), so I believe this report will be the final
one.

Related to the other report, there is some more missing documentation
regarding the :s word modifier.
If the line ends after "old", it is equivalent to :s/old/new/ (assuming old
and new do not contain '/').
Well, if `new' is null, the instances of `old' are deleted. That's
consistent with other history expansions. You can already omit the
trailing delimiter if that ends the line.
[root@localhost ~]# echo !:s
echo echo a b c
echo a b c
Technically, that's a bad substitution (csh throws an error), since it's
missing the delimiter. The readline code just lets it go; that's one of
the few places it's less strict than csh.
